This Crustless Quiche feels like a cheese topped mega treat, but served with salad (or new potatoes for dinner), it still makes a really light and fresh meal.

It’s packed with protein and veggies too, all of the good stuff in one place.

A no-pastry vegetarian quiche recipe is such a good basic go-to meal as you can vary the fillings to fit with any veggies you have in the fridge or freezer, as well as surplus eggs, so it’s a great way of avoiding wasting food.

I’ve used broccoli and peas in this dish because they go so well with the eggs and cheese, but you can really choose whatever you prefer (see below for some more filling ideas).

How we came up with this recipe

I wanted to adapt my lunchbox Mini Crustless Quiches recipe so we could enjoy it as a full meal, albeit with sliceable leftovers for packed lunches if needed.

I realised just how easy, healthy and delicious a crustless quiche could be, and that it serves as so many different types of meal (brunch, lunch, dinner, picnic, buffet dish…)

Not only that, it’s also a fantastic way of using up surplus food, making it super budget friendly.

I tested this plenty of times to get the flavours and consistency just right and effort low, making sure we could simply add some cooked vegetables into the dish, pour the egg mixture over the top and leave on its own to bake.

I hope you love it!

Crustless Quiche Ingredients Notes

  • Broccoli – We’re going to chop this into bite-sized florets. Make sure you do the same with any other veggies to add
  • Onion – You can either chop a fresh onion up or use the equivalent quantity in frozen, pre-chopped onion for speed
  • Eggs – I always use medium, free range in my recipes so bear this in mind when thinking about quantities
  • Cheese – Try and use something that has plenty of flavour, like cheddar, but you can go with your favourite. This should be grated for even distribution

How to make Crustless Quiche

  1. Soften the onions in oil in a frying pan, then add the broccoli for 4-5 minutes, followed by the peas for a further 3 minutes.
  2. Once softened, add the veggies into a shallow dish.
  3. Beat the eggs and pour over the vegetables. Sprinkle cheese over and season.
  4. Bake for 25-30 minutes in a preheated oven at 180C. Leave to cool for 5 minutes before slicing.

Hint: The cooked quiche should be cooked through but still a little wobbly.

Other filling options

You can get really experimental here and avoid being too precious.

  • This recipe is a win for using up whatever you have left over, so just go for it! I love anything with onions.
  • Peas, mint and feta cheese go really well together, as does spinach and feta (which is more like a crustless Spanakopita quiche).
  • You can also add in meat if you like.


In the fridge You can keep this recipe in the fridge for 3 days. Reheat fully before serving or enjoy it cold.

In the freezer This recipe freezes well. Just wait until it’s totally cold, wrap it up well and then put into a freezer proof container and freeze for up to 3 months. Defrost thoroughly before reheating in the microwave or eat it cold.

Top tipS


You’ll need quite a shallow dish for this. Make sure it’s not too big or your quiche will be flat. I like this 25cm Pyrex pie dish from Amazon.

Leave to cool

It’s best to leave the quiche to cool for 5 mins before cutting it as it will be much easier to slice.

Make ahead of time

Cold Crustless Quiche makes a brilliant packed lunch dish. Just allow it to cool fully, wrap it well and then store in the fridge for up to 3 days.


Is there a difference between a Crustless Quiche and a Frittata?

They can often have very similar ingredients, but traditionally a frittata would be cooked in a frying pan on the hob and finished under the grill, whereas a quiche is cooked in the oven.

Try my Smoked Salmon and Broccoli Frittata!

Is this a healthy quiche recipe?

Traditional quiches have a pastry base, which is packed with fats, and often the fillings are laden with heavy or double cream, which also adds to the calorie count.

Seeing as a Crustless Quiche omits the pastry and cream, plus has loads of vegetables, this is a lighter alternative.

Can I make a Crustless Quiche with meat?

Yes, you can add in meat if you don’t mind the quiche not being vegetarian. How about bacon and mushroom? Or pea and ham? You can also mix up the type of cheese you use too.

Do you have any more brunch ideas?

I do! Try out my Healthy Breakfast Muffins, my Shakshuka, simple Slow Cooker Salmon or my Creamy Salmon Bake.

How about other easy vegetarian meals?

I have lots! Try my 15 minute Halloumi Burger recipe, my super simple Chickpea Curry or one pan Tomato Pasta.

Is this a gluten free recipe?

Yes, this is a gluten free quiche recipe.

What is the difference between a quiche and a crustless quiche? ›

Crustless quiche is similar to a traditional quiche where it has savory egg custard loaded with cheese and mix-ins, but it's baked without a pie crust. It's the easygoing egg bake answer to practically every breakfast problem I've ever seen.

What not to put in quiche? ›

Avoid Fillings That Are Too Wet

"Some vegetables, such as sliced large tomatoes or raw zucchini, have a high water content and will make your quiche soggy (even if you follow all steps to avoid this!)," Davila notes.

Why is my crustless quiche soggy? ›

According to Real Simple, this typically occurs when adding too-wet ingredients to the quiche filling, layering the egg custard with, for example, large slices of raw tomato or raw zucchini. These vegetables, while tasty, have a high water content when raw, which will weep into the quiche as it bakes.

What are 3 main differences between a frittata and a quiche? ›

Origin: Frittata is an Italian dish whereas quiche is a French dish. Crust: A quiche has crust while a frittata does not. Sometimes, quiche is baked without crust. Base Ingredients: While both frittatas and quiches are made with eggs, quiche is made with an egg custard, which also includes cream or milk.

Is heavy cream better than milk in quiche? ›

Heavy Cream and Milk – For the best tasting quiche, use a combination of whole milk and heavy cream. (Or simply use half-and-half.) Using just heavy cream produces an overly thick filling. Whole milk is great, but a combo of heavy cream and milk is better.

What Italian egg dish is similar to a crustless quiche? ›

A frittata is an Italian egg dish that is like an omelet or quiche but lazy and forgiving. It's lazy because the recipe is easy, and you don't have to do the tricky omelet fold. It's also forgiving since you don't have to make a crust and uses no cream or milk, unlike an omelet or quiche.

Should quiche be cooked at 350 or 375? ›

BAKE in center of 375°F oven until center is almost set but jiggles slightly when dish is gently shaken and knife inserted near center comes out clean, 30 to 40 minutes.

Do you need to prebake pie crust for quiche? ›

Some recipes like quiches recommend partially cooked pie shells because the baking time wouldn't be long enough to fully cook the dough otherwise. Pre-baking a crust can ensure that your pie or tart crust will be fully baked and browned, and not soggy.

Can you put too many eggs in a quiche? ›

Using too many eggs in the custard results in a quiche that rubbery and too firm when baked, while not using enough will prevent the custard from setting. Follow This Tip: Remember this ratio: 1 large egg to 1/2 cup of dairy.

Why is my crustless quiche flat? ›

Too much liquid - the batter should not be runny so maybe you could reduce the liquid content just a little. Too much sugar in the cake can also sink the cake. In your recipe you use 2 cups of sugar for 2 cups of flour...

How long does crustless quiche last in fridge? ›

TO STORE: Refrigerate quiche in an airtight storage container for up to 3 days. TO REHEAT: Rewarm leftovers in a pie dish in the oven at 350 degrees F. TO FREEZE: You can freeze a crustless quiche.

How do you crisp the bottom of a quiche? ›

Blind bake the crust!

This avoids the soggy bottom problem by making the crust perfectly firm before you add the filling. This is important for a custard pie like a quiche because the filling is so wet. If you don't blind bake, you'll get soggy bottom crust for sure (we did).

What's the difference between quiche and quiche lorraine? ›
